Good information - the reason I asked about the stand alone unit is I have a particular interest in keeping the garage comfortbale because this is where I plan to put my cat litter boxes.

I have cats and their litter boxes are in a storage area in the basement (I presently live in IL - going to move next year, I hope!!!).

I don't want boxes in the living area at all so the garage seems to be the logical space. I just need to get creative on how I'm gong to develop a way for them to access the boxes in a somewhat enclosed area in the garage (some kind of cat door that leads to a contained area where they can do their business).

But these postings about different options is very helpful. Thanks
